BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates generally to urine strainers used by patients with kidney stones and urine samplers. More particularly, this invention relates to urine strainers designed for the unique physical needs of female users and also urine samplers for use by anyone that needs to produce a urine sample.

Description of Related Art

There are many potential causes of kidney stone formation. In general they result from a super concentration of chemicals in the urine that result in crystals being formed. This may be brought on by one or more of the following: a family genetic predisposition to form stones, an excess of calcium or certain other minerals in the diet (sometimes due to local geographic water or soil conditions), intake of excess uric acid, certain medications, Vitamin C, or Vitamin D, a diet of fruits and vegetables high in oxalate (a by-product of metabolism), long term dehydration (possibly due to inadequate intake of fluids) and its resulting concentration of urine, urinary infection, living in an area where high temperatures cause sweating and loss of fluids, or possibly, just leading a sedentary (low physical activity) lifestyle.

Kidneys eliminate byproducts of metabolism. This means that kidneys are constantly collecting the major ingredients for kidney stones, including: calcium, oxalate, and uric acid. Ideally these minerals are kept in suspension until they are passed out of the body. Individuals who have excess metabolic by-products in insufficient fluid (urine) are particularly prone to kidney stone formation.

The excess concentration of metabolic byproducts in the urine can cause these minerals to move out of suspension and crystallize. These small crystals that precipitate out of the super saturated urine will usually pass out through the urinary tract, but they may begin to clump together. Any existing crystal makes it easier for other crystals to form. If they stay in the kidney very long, the crystals gradually grow larger and larger until they become a kidney stone so large that it cannot pass comfortably through the urinary tract.

Since kidney stones may contain a variety of crystalline and noncrystalline materials it is important to know the composition of a kidney stone in order to guide clinical decisions. Although urine composition provides information on the possible composition of a patient's stone, this is not perfectly predictive of the stone type and, at times, can be misleading. Thus, instructing the patient to retrieve a passed stone or instructing the urologist, who is performing a stone-related procedure, to save and send a stone fragment for analysis is an important part of the approach to prevent recurrent stone formation. The stone composition may also influence the choice of urologic intervention.

The most common crystalline materials found in kidney stones may include calcium oxalate, calcium phosphate, uric acid, and struvite. It is not uncommon for a stone to contain more than one crystalline component. Noncrystalline materials found in kidney stones may include proteins and blood. Some laboratories report the composition of the infection nidus (if present) separately from the composition of the body of the stone.

Thus, patients with kidney stones are frequently asked by their urologists to collect kidney stones as they are passed in order to perform a laboratory analysis on their composition. Most conventional devices used to gather kidney stones are little more than a funnel shaped strainer with a fine mesh to allow urine to pass through while holding back the kidney stones via the fine mesh. However, such conventional urine strainers tend to be much easier for male patients than female patients.

As one can imagine it is much easier for men to direct a urine stream into a strainer than it is for women. Merely obtaining a urine sample also presents difficulties for women for similar reasons. Accordingly, there exists a need in the art for urine strainers and samplers better suited for use by female patients.

BRIEF SUMMARY OF THE INVENTION

The present invention includes embodiments of strainers used to gather solids from voided urine. Particular embodiments include urinary bowl strainers, hand-held strainers and disposable hand-held urine strainers, all of which are particularly useful for gathering kidney stones passed in urine that are intended for verification of passing said kidney stones, and for laboratory analysis which may be used to guide clinical treatment to prevent recurrent kidney stone formation.

The present invention further includes embodiments of disposable urine samplers which are used to obtain urine samples. The embodiments of disposable urine samplers generally include a handle leading to a urine cup receptacle. The embodiments of urine samplers disclosed herein are used by patients who have been instructed or otherwise need to produce a urine sample in a urine sample cup. The embodiments of urine samplers disclosed herein help prevent accidental urination on the hands or fingers of the user during the urine sampling process.

The embodiments of urine strainers and samplers disclosed herein are particularly adapted for use by female patients, though male patients may also use the devices. Because each embodiment disclosed may be used by either gender, they may find universal application as urine strainers and samplers. The universal urine strainers and samplers disclosed herein are thus advantageous over conventional strainers and samplers that are available in the market to date, which are generally convenient only for males.

Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of embodiments of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention include a disposable urine strainer, a bowl strainer and a hand-held strainer, all of which are particularly useful for gathering kidney stones passed in urine that are intended for laboratory analysis to further guide clinical treatment to prevent recurrent kidney stone formation. An embodiment of a disposable urine sampler is also disclosed. The embodiments of urine strainers and samplers disclosed herein are particularly adapted for use by female patients, but may also be used by male patients.

FIGS. 1A-1E are perspective, side, top, front and cross-sectional views, respectively, of an embodiment of a urinary bowl strainer 100, according to the present invention. Bowl strainer 100 may be configured for use with any standard toilet (not shown). More particularly, the embodiment of a bowl strainer 100 is configured for placement between the toilet bowl and toilet seat (neither shown). Bowl strainer 100 is ideal for use at home where the patient may spend considerable time and experience multiple voids, and where it may be most convenient to gather passed kidney stones. Furthermore, the embodiment of a bowl strainer 100 shown in FIGS. 1A-1E is easy for female patients to use because being seated is the conventional female method for voiding urine.

Bowl strainer 100 may be round or oval (as shown in FIG. 1C) in shape, fitting at least partially inside the radiance of a standard round or oblong toilet. Bowl strainer 100 may include a plurality of support members 102, which can serve as handles when placing or retrieving the bowl strainer 100 from its position on a toilet (not shown). These support members 102 may be placed directly along the top of the toilet bowl (not shown) after the lid and toilet seat (neither shown) have been raised, and the toilet seat can be positioned on top of the support members 102 to hold the bowl strainer 100 in place during use. Using this particular embodiment of a bowl strainer 100, there is no requirement for the user to hold or manage the bowl strainer 100 while effecting void. The center (shown generally at arrow 110) of the bowl strainer 100 device is generally recessed and comprised of a bowl-shaped frame 104 with an opening 106 covered by a flexible fine thin mesh 108 to allow for fluid (urine) to pass through, while retaining any items contained in the urine stream to be retained inside the bowl strainer 100.

Bowl strainer 100 may be formed of lightweight plastic or other suitable materials that are washable and re-usable as needed. Bowl strainer 100 may also be made of disposable materials for singular use in hospital, clinical or home use. The bowl-shaped frame 104 may have straight line cross-section 112 as shown in the illustrated embodiment of a bowl strainer 100 in FIGS. 1B, 1D and 1E. However, various other cross-sections, for example and not by way of limitation, rounded or curved (see, e.g., 412 in FIGS. 4B, 4D and 4D and discussion below), according to other contemplated embodiments.

FIGS. 2A-2E are perspective, top, side, front and cross-sectional views, respectively, of an embodiment of a hand-held urine strainer 200, according to the present invention. Hand-held urine strainer 200 is configured for use while standing or squatting over a toilet bowl (not shown). Hand-held urine strainer 200 may be used by male and female patients. But, because of its shape, hand-held urine strainer 200 is particularly adapted for use by female patients. The hand-held urine strainer 200 is sized to be portable and is configured to reusable by simply washing in water. Additional features of the embodiment of hand-held strainer 200 follow.

Hand-held urine strainer 200 may have a rounded-rectangle-shaped rim 214 at the top of a generally bowl-shaped frame 204 as viewed from the top in FIG. 2B. The rounded-rectangular-shaped rim 214 includes two opposed convex lips 216 and two opposed concave lips 212. The lips 212 and 216 of rim 214 are rounded and not sharp-edged. The two opposed concave lips 212 are specially adapted to fit, and may be held, between the thighs of a female patient during urination. Hand-held urine strainer 200 may further include a protruding handle 202 extending from one of the two opposed convex lips 216. The hand-held urine strainer 200 is configured to gather urine inside the rim 214 and guide it toward the recessed area in the center 210 of the hand-held urine strainer 200.

The handle 202 may be used by the patient to control the placement of the hand-held strainer 200 during use. Hand-held urine strainer 200 may further include a generally bowl-shaped frame 204 extending from the rim 214 down to a circular opening 206. The circular opening 206 located within the recessed center 210 may be comprised of a flexible thin fine mesh for straining fluid voids. Handle 202 may extend from rim 214 and handle base 218. Handle 202 may be configured with any suitable shape and length according to various embodiments. More particularly, the shape and length of handle 202 is specifically designed for female patients to avoid urinating on their own hand, or other body part, or on the toilet, or rim thereof, and to collect any items passed through the urine stream such as kidney stones for analysis.

FIGS. 3A-3F are perspective, top, rear, side and handle perspective views, respectively, of an embodiment of a disposable hand-held urine strainer 300, according to the present invention. Like the hand-held urine strainer 200 embodiment, the disposable hand-held urine strainer 300 is also portable. Disposable hand-held urine strainer 300 is configured for use while standing or squatting over a toilet bowl (not shown). Disposable hand-held urine strainer 300 may be used by male and female patients. But, because of its shape, Disposable hand-held urine strainer 300 is particularly adapted for use by female patients. The opposed curved walls 312 together form a football-shaped cross-sectioned frame 304. The football cross-sectioned frame 304 has a football cross-sectioned opening 306 that is covered at the bottom end 310 by a flexible fine thin mesh 308. The opposed curved walls 312 are intentionally narrow relative to the overall length from tip 314 to handle base 316 in order to allow the disposable hand-held urine strainer 300 to be close to the inner thighs of female patients during use. Because of its lightweight construction, disposable hand-held urine strainer 300 is further configured to be disposable and not reused.

Disposable hand-held urine strainer 300 is a lightweight portable device for use in straining fluids and capturing any items contained in the urine stream such as kidney stones for analysis. Disposable hand-held urine strainer 300 may be constructed of any suitable disposable materials, for example and not by way of limitation, lightweight milled paper or cardboard. According to one embodiment, disposable hand-held urine strainer 300 may be supported by thin wire located at the vertex, or fold lines, or bottom end of the milled paper to ensure flexibility for handling, according to various embodiments of the present invention.

The center opening 306 may be any suitable shape, for example and not by way of limitation, football cross-sectioned or oval in shape as depicted in FIGS. 3A, 3B and 3E. The center opening 306 at the recessed bottom 310 may be covered with a flexible fine thin mesh 308. A handle 302 may be attached to the football cross-sectioned frame 304 at the handle base 316 and can be folded for transport and easy storage. When the handle 302 is unfolded and out, it gives the user ample length for holding and placement of the strainer 300 inside the toilet bowl and/or between the user's thighs, to collect the void. The handle length, orientation and strainer shape are specifically designed for female use, to avoid the female patient getting any urine on their hand or elsewhere while performing urination. For example, the handle 302 may be disposed at any suitable angle, Θ, relative to frame 304 as shown in FIG. 3E. Once collected, any items retained inside the mesh portion can be retained in a separate bag or container for transport to a medical professional, or analyzed by the user and then discarded with the disposable hand-held urine strainer 300.

FIGS. 4A-4E illustrate another embodiment of a urinary bowl strainer 400, according to the present invention. More particularly, FIGS. 4A-4E are perspective, front, top, side and cross-sectional views, respectively, the embodiment of a urinary bowl strainer 400, similar to the embodiment of bowl strainer 100 shown in FIGS. 1A-1E. Bowl strainer 400 may also be configured for use with any standard toilet (not shown). Bowl strainer 400 is configured for placement between the toilet bowl and toilet seat (neither shown). Bowl strainer 400 is ideal for use at home where the patient may spend considerable time, experience multiple voids, and where it may be most convenient to gather passed kidney stones. Furthermore, the embodiment of a bowl strainer 400 shown in FIGS. 4A-4E is easy for female patients to use because being seated is the conventional female method for voiding urine.

Bowl strainer 400 may be round or oval (as shown in FIGS. 4A and 4C) in shape, fitting at least partially inside the radiance of a standard round or oblong toilet. Bowl strainer 400 may include a plurality of support members 402 (four shown), which can serve as handles when placing or retrieving the bowl strainer 400 from its position on a toilet (not shown). These support members 402 may be placed directly along the top of the toilet bowl (not shown) after the lid and toilet seat (neither shown) have been raised followed by the toilet seat positioned on top of the support members 402 to hold the bowl strainer 400 in place during use. Using bowl strainer 400, there is no requirement for the user to hold or manage the bowl strainer 400 while effecting void. The center, shown generally at arrow 410 (FIGS. 4A and 4C) of the bowl strainer 400 includes a generally recessed and bowl-shaped frame 404 with an opening 406 covered by a flexible fine thin mesh 408 to allow for fluid (urine) to pass through, while retaining any items contained in the urine stream to be retained inside the bowl strainer 400. Note that the opening 406 and mesh 408 are both smaller than opening 106 and mesh 108 in bowl strainer 100. This smaller sizing in the embodiment of bowl strainer 400 may have the advantage of lower cost and yet still maintains the functionality versus the embodiment of bowl strainer 100.

FIG. 4F is a plan view of an embodiment of the flexible fine thin mesh 408 of the embodiment of a urinary bowl strainer 400 shown in FIGS. 4A-4E, according to the present invention. Mesh 408 may be formed of any suitable material that allows fluid (urine) to pass through the mesh 408 and into the toilet bowl or other urine receptacle, while retaining any items (kidney stones, etc.) contained in the urine stream. According to one embodiment, mesh 408 may be formed of 800 micron polypropylene mesh having 58% open area, with hole size 0.032″×0.032″ and having thickness, 0.016″. It will be understood that the particular dimensions of mesh 408 illustrated in FIG. 4F are configured to allow mesh 408 to cover opening 406. According to the illustrated embodiments, opening 406 and its corresponding mesh 408 are generally “guitar pick”, or roughly D-shaped, in plan view. However, it will further be understood that the particular shape of opening 406 and its corresponding mesh 408 may be of any suitable shape. Mesh 408 may be adhered to bowl strainer 400 in any manner known to those skilled in the art including, for example and not by way of limitation, adhesive, thermal fusing, tape, etc.

One additional advantage of the embodiment of bowl strainer 400 versus bowl strainer 100 is that the bottom portion that does not have mesh 408 can be used to obtain a stool sample if properly placed on a toilet while allowing urine to strain out. A urine strained stool sample may also be obtained using the embodiment of bowl strainer 100, however mesh 108 may be required to support the stool, which may be undesirable for durability of the reusable bowl strainer 100.

Bowl strainer 400 may be formed of lightweight plastic or other suitable materials that are washable and re-usable as needed. Bowl strainer 400 may also be made of disposable materials for singular use in hospital, clinical or home use. The bowl-shaped frame 404 may have curved line cross-section 412 as shown in the illustrated embodiment of a bowl strainer 400 in FIGS. 4B, 4D and 4E. However, various other cross-sections, for example and not by way of limitation, straight line (not shown, but see 112 in FIGS. 1B, 1D and 1E), according to other contemplated embodiments.

FIGS. 5A-5E illustrate another embodiment of a hand-held urine strainer 500, according to the present invention. More particularly, FIGS. 5A-5E are perspective, top, side, front and handle-edge views, respectively, of the embodiment of a hand-held urine strainer 500. The embodiment of hand-held urine strainer 500 is similar to the embodiment of hand-held urine strainer 200. Hand-held urine strainer 500 is also configured for use while standing or squatting over a toilet bowl (not shown). Hand-held urine strainer 500 may be used by male and female patients. But, because of its shape, hand-held urine strainer 500 is particularly adapted for use by female patients. The hand-held urine strainer 500 is sized to be portable and is configured to reusable by simply washing in water. Additional features of the embodiment of hand-held strainer 500 follow.

Hand-held urine strainer 500 may have a generally bowl-shaped frame 204 with a handle 502 extending from a central end 520 of rim 514 at handle base 518. Rim 514 may have a generally rounded-rectangular-shape as viewed from the top in FIG. 5B. More particularly, rim 214 includes two opposed convex lips 516 located at central 520 and distal 522 ends. Rim 514 further includes two opposed concave lips 512 between the central 520 and distal 522 ends. The lips 512 and 516 of rim 514 are generally rounded and not sharp-edged. The two opposed concave lips 512 are specially adapted to fit, and may be held, between the thighs of a female patient during urination.

As noted above, hand-held urine strainer 500 may further include a protruding handle 502 extending from one of the two opposed convex lips 516 at central end 520. More particularly, the handle base 518 meet one of the two opposed convex lips 516 at the central end 520. According to the illustrated embodiment of hand-held urine strainer 500 a hole 526 may be formed near the proximate end 524 of handle 502, see FIGS. 5A-5D. Hole 526 may be used for hanging strainer 500 for storage or to dry after washing for reuse. According to various embodiments, handle 502 may be angled at a preselected angle, ϕ, which is measured from a line perpendicular to the flat or planar surface of bottom end 528, see FIG. 5C. This preselected angle, ϕ, may range from 0°-45° in order to facilitate placement of the hand-held urine strainer 500 comfortably during use.

In operation, hand-held urine strainer 500 is configured to be positioned for use with the bottom end 528 toward ground to take advantage of gravity. When positioned for use, hand-held urine strainer 500 is configured to gather urine inside the bowl-shaped frame 504 and guide it toward the recessed area in the center 510 of the hand-held urine strainer 200. During use, urine from a patient's urethra is directed toward the recessed area in the center 510.

Handle 502 may be used by the patient to control the placement of the hand-held strainer 500 during use. The generally bowl-shaped frame 504 of hand-held urine strainer 500 extends from the rim 514 down to the recessed area in the center 510 which forms the bottom end 528 of strainer 500. The recessed area in the center 510 may further include a generally D-shaped opening 506, see particularly FIGS. 5B and 5E. The D-shaped opening 506 located within the recessed center 510 may be covered with a flexible thin fine mesh 530 for straining fluid voids.

Handle 502 may extend from rim 514 and handle base 518. Handle 502 may be configured with any suitable shape and length according to various embodiments. More particularly, the shape and length of the handle 502 is specifically designed for female patients to avoid urinating on their own hand(s), or other body part, or on the toilet, or rim thereof, and to collect any items passed through the urine stream, but held back by fine mesh 530 such as kidney stones for analysis.

FIG. 5F is a plan view of an embodiment of the flexible fine thin mesh 508 of the embodiment of a hand-held urine strainer 500 shown in FIGS. 5A-5E, according to the present invention. Mesh 508, like mesh 408 (FIG. 4F) may be formed of any suitable material that allows fluid (urine) to pass through the mesh 508 and into the toilet bowl or other urine receptacle, while retaining any items (kidney stones, etc.) contained in the urine stream. According to one embodiment, mesh 508 may be formed of 800 micron polypropylene mesh having 58% open area, with hole size 0.032″×0.032″ and having thickness, 0.016″. It will be understood that the particular dimensions of mesh 508 illustrated in FIG. 5F are configured to allow mesh 508 to cover opening 506. According to the illustrated embodiments, opening 506 and its corresponding mesh 508 are both generally “D-shaped” in plan view. However, it will further be understood that the particular shape of opening 506 and its corresponding mesh 508 may be of any suitable shape. Mesh 508 may be adhered to hand-held urine strainer 500 in any manner known to those skilled in the art including, for example and not by way of limitation, adhesive, thermal fusing, tape, etc.

Another embodiment of a hand-held urine strainer 600 is disclosed. FIG. 6A is a plan view of an embodiment of pattern, shown generally at arrow 604, for a disposable hand-held urine strainer 600, according to the present invention. The embodiment of a pattern 604 for strainer 600 is configured to be cut from lightweight milled paper or cardboard and folded into the shape or assembled frame 605 shown in FIGS. 6B and 6C. More particularly, FIGS. 6B and 6C are left perspective and right side views of the embodiment of a frame 605 for a disposable hand-held urine strainer 600 as cut and folded from the pattern 604 shown in FIG. 6A, but without a fine mesh 608 placed over the circular opening 606. Accordingly, this embodiment of a disposable hand-held urine strainer 600 may be formed of essentially two separate components, (1) a pattern 604 that is folded into an assembled frame 605 having a circular opening 606 and (2) a fine mesh 608 placed over the circular opening 606.

Adhesives may further be used to hold the folded pattern 604 together along with cut-outs and tabs in various locations in order to obtain assembled frame 605. However, the entire strainer 600 is configured to be simply folded into the shape shown in FIGS. 6B and 6C. Once folded, strainer 600 may be used by a patient to strain urine during bladder elimination. Then kidney stones (if any) may be retrieved from within the strainer basin for further analysis and then strainer 600 may be disposed in a waste receptacle.

As noted above, a completed embodiment of a disposable urine strainer 600 further includes a fine mesh 608 (not shown in FIGS. 6A-6C) placed over the circular opening 606. According to one embodiment, mesh 608 may be formed of 800 micron polypropylene mesh having 58% open area, with hole size 0.032″×0.032″ and having thickness, 0.016″. According to another embodiment, mesh 608 may be circular in shape and sized to cover opening 606. However, mesh 608 may be any shape, e.g., square, rectangular, etc., that is large enough to cover opening 606, according to still other embodiments. Mesh 608 may be adhered to disposable urine strainer 600 in any manner known to those skilled in the art including, for example and not by way of limitation, adhesive, thermal fusing, tape, etc.

As further shown in FIG. 6A, an embodiment of pattern 604 for a disposable urine strainer 600 may further include a generally rectangular-shaped floor panel 610 in which an opening 606 and four slots 624 are cut. The embodiment of a pattern 604 for a disposable urine strainer 600 may further include opposed side panels 612, a front panel 614 and rear panel 616. More particularly, the front panel 614 may further include opposed front corner panels 618 each having a tab 620. Similarly, the rear panel 616 may further include opposed rear corner panels 622, each having a tab 620. During assembly of disposable urine strainer 600, panels 612, 614 and 616 are folded in toward circular opening 606 on floor panel 610, with corner panels 618 and 622 inside side panels 612 such that tabs 620 may be inserted in to slots 624. In this folded and tab-slotted configuration the frame 605 of disposable urine strainer 600 is essentially assembled.

An embodiment of handle, shown generally at arrow 602, may include first, second and third panels 626, 628 and 630, respectively. During assembly, a partial cut 632 (see FIG. 6A) between the first 626 and second 628 panels allows the first panel 626 to be folded up onto the second panel 628 followed by folding first and second panels 626 and 628 onto third panel 630. By folding first through third panels 626, 628 and 630 on top of each other, handle 602 acquires added torsional stiffness for use as a handle during use.

Though FIGS. 6A-6C illustrate an assembled frame 605 (namely, a strainer 600 without mesh 608) it will be understood that by simply adhering mesh 608 over opening 606, a complete strainer 600 is obtained. The dimensions of the embodiment of pattern 604 are merely exemplary and not critical to the functioning of the strainer 600. Accordingly, it will be understood that any of the dimensions and features disclosed may be varied to any suitable degree as long as the resulting strainer 600 is sized for use by a patient to strain urine, according to other embodiments of the present invention.

A particularly useful feature of disposable urine strainer 600 is that it can be folded nearly flat and conveniently packaged for retail sale or carried by the user. FIG. 6D is a perspective view of an embodiment of a disposable urine strainer 600 shown in FIGS. 6A-6C, folded for storage, according to the present invention. As shown in FIG. 6D, pattern 604 may be folded as shown, and later unfolded and assembled into the frame 605 shown in FIGS. 6B and 6C. It will also be understood that a plurality of folded disposable urine strainers 600 may be packaged in an appropriately sized box for carrying by the user. An appropriate box size may be configured to carry any suitable number of folded strainers 600, for example and not by way of limitation, 2-12 strainers 600. By having a portable supply of urine strainers 600, the user can have ready access strainers 600 to strain urine while traveling or away from home.

The embodiments of urine strainers 100, 200, 300, 400, 500 and 600 disclosed above are all useful for straining urine and are particularly useful for female patients because of the inherent anatomical difficultly in directing a urine stream. But, it will be understood that male patients can also use any one of the embodiments of urine strainers 100, 200, 300, 400, 500 and 600 disclosed above. The hand-held urine strainer embodiments 200, 300, 500 and 600 disclosed above are particularly useful in preventing the undesirable possibility of urinating on one's own hands or fingers during bladder elimination, because of the respective handles 202, 302, 502 and 602 that hold the catch-basin and strainers away from the patient's urethra and urine stream during elimination. For this very same reason, it is desirable to have a urine sampler with a handle that serves the same function, but in the context of obtaining a urine sample, rather than straining the urine to obtain a particular residue. An embodiment of such a urine sampler will now be disclosed.
